This can happen over time, the connection points get a little resistance build up and discolor from the heat. This resistance comes from the moisture, steam and spills. The protective devices on the board and machine are designed to fail safe.

I would suggest replacing the board after inspecting the wiring harness from the board down through the door and to the motor.

Quick fix?


Hi Mick. Well, it's rare that the main fuse fixes TVs any more. Look for burn marks on the integrated circuits (ICs), or capacitors (sorta shaped like a AA battery standing on end) that are domed on top. If you find either of those, that board needs changed, but if you do see burnt ICs, there might be other boards affected. Sometimes it's better to have a professional look at it.

Iberna oven ,when i switch on the oven it chips the fuse box out


First of all check the inside of the cooking area for chips in the paint and burn marks. If there are none then you may repair this unit. Open it up and check the many thermal overloads for open circuit. Then check for burned wires and repair any if found. Then replace the fuse if blown. Then change the magnetron and possibly the capacitor. Also verify that the door closes properly and that the circuit board has no burned components or burned circuit traces. Sometimes the relays stick and need replacing but that would not cause the breaker to trip.

I have aVizio VX42L HDTV10A. was watching a show when we heard a loud pop.Then all went dark. Would not turn back on. I took off the back cover and found the ceramic fuse was blown on the board # DPS-283AP...


This means you have a dead short, It is probably a Diode in the power supply area, but without testing board you don't know. If you know basic electronics, i would say check all diodes in power supply and look hard for something burnt and replace that also. Or just replace power board, check shopjimmy.com

The washer was in spinning cycle, when I smelled plastic burning, then it stop all together. I was able to turn it off, but now it doesn't do anything. What could this be?


It will be good to start with looking into the washer with the power switched off smelling for the source that burnt. this will be easy to find and the possible area could be the power section in the main board- the control board.
Once you have isolated the burnt component we can decide if the part alone can be changed or the full board needs a change.
The motor and the drain pump also must be checked for any burnt outs.

When the fridge is turned on, it begins to beep constantly and does not stop until we switch it back off. We had moved the fridge about because we were shifting it to the kitchen and there was water...


HI, this beeping is signaling an issue that concerns the main control board. The control board may have sustained some serious damage during the move. Have it replaced asap. This spillage may have dripped onto the board itself, thus, causing a short when power was introduced after the unit was settled in its new arrangement.

You can visibly inspect the board for water damage or burn marks on the circuit layout.

An Rca tv turns on then immediately turns off. Rca tv model number 20F512T. It has picture, audio, and no blinking lights. I've checked the main board and no problem what so ever. Nothing burned or loose....


If it turns off going standby, and led is on, then it is on protect, and remaining parts must be tested.

If it turns off completely, and you can restart it with the On button, then the board with controls is faulty.
If it does switch off completely (no light), and only comes back on after unplugging power cord for a while, then there is a different internal fault that is not starting protection circuit , but causing shutdown.
After double checking the PSU board, you will have to test a couple of ICs on main controller board, the deflection circuit and flyback transformer. Check also for broken solder joints and thaces of shorts on all boards and components (eg. burnt areas, blown capacitors), as a short can potentially cause sudden shut down.

Here schematics.

Here all parts for your TV.
